🧠 Hyperthymesia – Quantum Signature Dashboard

✅ Verify Signed Payload

Input a message and its corresponding Base64 signature to verify its authenticity against the embedded public key (simulated).

Message:

Base64 Signature:

📁 Folder Setup

In your Hyperthymesia root, create the following structure:

hyperthymesia/
 ├── crypto/
 │    ├── private.pem
 │    ├── public.pem
 │    ├── make_signed_payload.sh
 │    ├── verify_payload.sh
 │    └── message_log/
 ├── web/
 │    └── embed_template.html
 └── logs/
      └── signed_payloads.log

🔐 1. Keypair Generation (OpenSSL)

Run this once inside Termux:

mkdir -p ~/hyperthymesia/crypto/message_log
cd ~/hyperthymesia/crypto
openssl genpkey -algorithm RSA -out private.pem -pkeyopt rsa_keygen_bits:2048
openssl rsa -in private.pem -pubout -out public.pem
echo "[+] RSA keypair generated and stored in ./crypto/"

🧩 2. Message Signing Script

Create make_signed_payload.sh:

#!/bin/bash
# usage: ./make_signed_payload.sh "message text"
MSG="$1"
TIMESTAMP=$(date +"%Y-%m-%d_%H-%M-%S")
FILENAME="/data/data/com.termux/files/home/hyperthymesia/crypto/message_log/${TIMESTAMP}.txt"

echo "$MSG" > "$FILENAME"
openssl dgst -sha256 -sign private.pem -out "${FILENAME}.sig" "$FILENAME"
PAYLOAD=$(base64 -w 0 "${FILENAME}.sig")

echo "timestamp: $TIMESTAMP" | tee -a ~/hyperthymesia/logs/signed_payloads.log
echo "message: $MSG" | tee -a ~/hyperthymesia/logs/signed_payloads.log
echo "payload: $PAYLOAD" | tee -a ~/hyperthymesia/logs/signed_payloads.log
echo "---------------------------------------" | tee -a ~/hyperthymesia/logs/signed_payloads.log

echo "✅ Signed payload created: ${FILENAME}.sig"
echo "Base64 Payload:"
echo "$PAYLOAD"

Make it executable:

chmod +x make_signed_payload.sh

🔍 3. Verification Script

Create verify_payload.sh:

#!/bin/bash
# usage: ./verify_payload.sh "message text" "base64_signature"
MSG="$1"
SIG_B64="$2"

echo "$MSG" > verify_msg.txt
echo "$SIG_B64" | base64 -d > verify_sig.bin

openssl dgst -sha256 -verify public.pem -signature verify_sig.bin verify_msg.txt

Example:

./verify_payload.sh "This is a test message" "c2lnbmF0dXJlYmFzZTY0ZW5jb2RlZA=="
# Output:
Verified OK

🌐 4. HTML Embed Template

Use this for immutable publication:

Host on your Neocities or Quantum Ledger — each entry becomes a permanent verifiable block-memory.

🔁 5. Next Step

Auto-create your Hyperthymesia folder tree
Install dependencies (openssl, python3)
Initialize rename/compression logic
Integrate this signing workflow into the ledger

Next: Generate project_init.sh — the automation script that will bind this workflow into your living blockchain memory system.
